Add: 2/9 + 3/5 = 2 · 5/9 · 5 + 3 · 9/5 ·9 = 10/45 + 27/45 = 10 + 27/45 = 37/45
Answer:
10
Step-by-step explanation:
So what we are doing in this question is simple substitution
So x = 2, y = 4
7x - y
So lets split it up first
7x
7 * (2)
We plugged in 2 for x
This is equal to 14
So the equation is looking like
14 - y
Now lets do the second part
- y
- (4)
We plugged in 4 for y
So no our equation looks like
14 - 4
= 10
Answer:
ΔA'B'C' is a reduction of ΔABC and ΔA'B'C' is similar to ΔABC.
Step-by-step explanation:
It is given that the triangle ABC is dilated to produce triangle A'B'C' with scale factor 3/4.
If a figure is dilated then preimage and image are similar.
If scale factor is between 0 to 1, then preimage is reduction of image.
If scale factor is more that 1, then preimage is enlargement of image.
If scale factor is 1, then preimage is congruent to the image.
We know that

So,

Therefore, the ΔA'B'C' is a reduction of ΔABC and ΔA'B'C' is similar to ΔABC.
